Recall the beam of light travelling down the well in Syene. Extend that beam to the center of Earth. Also extend the pole’s axis to the center of Earth. These two extensions are represented by dashed lines in Figure 1. The intersection of these two lines forms an angle . at the Earth’s center. Use basic geometry to find the relation between angles . and -. Calculate the angle . in radians: . = XXXXXXXXXX .
Figure in plane geometry formed by two rays or lines that share a common endpoint, called the vertex. The angle is measured in degrees using a protractor. The different types of angles are acute, obtuse, right, straight, and reflex.
